Reserved Parameters

Parameters of custom manager pages and other integrations are free, with a few exceptions.

Reserved parameters in the manager¶

The manager uses these parameters:

• a - the action or controller
• namespace - the namespace the action belongs to; defaults to core when omitted
• context_key - one of your contexts (e.g. “web” or “mgr”)
• wctx - the “working context”: the context the current item belongs to, rather than “mgr”
• class_key - a class name, e.g. when creating a Weblink or static resource
• id - the ID a certain action or controller defaults to

action is not a manager parameter — the manager only reads a. Connectors use action to select a processor.

System settings that affect manager routing and assets: manager_theme (picks the theme whose controllers/ and templates/ directories are searched first), welcome_action (the action of the manager’s Welcome page), and manager_path / manager_url (the physical and URL locations of the manager).

Reserved parameters in the front-end¶

• q - with friendly URLs enabled, routes a request to the right resource. Changeable via the request_param_alias system setting, but leave it unchanged.
• id - with friendly URLs disabled, fetches the current resource. Changeable via the request_param_id system setting, but leave it unchanged.

Reserved $_SESSION variables¶

• cultureKey
• all parameters prefixed with modx.
